Large numbers of Acacia cyclops trees are dying along the coastal plains of the Eastern and Western Cape Provinces of South Africa. Acacia cyclops A. Cunn. The genus was previously typified with the African species Acacia scorpioides (L.) W.F.Wright, a synonym of Acacia nilotica (L.) Delile. Acacia cyclops A. Cunn. The seeds remain viable in the soil for many years. It is often claimed that invasions increase fire hazard through changing vegetation structure and increasing fuel loads. Flowering stage green buds, yellow bus, open flowers, senescing flowers often present at the same time, and not easily seen from a distance. Almost all wattles have cream to golden colored flowers. ex G. Don, is a shrubby evergreen tree (1.5–6 m high), originating from south-western Australia. ex G. Don (Fabaceae, Mimosoideae), originating from Western Australia, is a serious environmental weed in South Africa. Two of the most successful invasive plant species in the fynbos are Acacia cyclops (rooikrans) and Acacia saligna (Port Jackson willow). Once established, it is difficult to remove or replace. Flowerheads cylindrical, galls on stems: Acacia stricta leaves: Acacia stricta flowers: Distribution. It is found along the west coast of Western Australia as far north as Jurien Bay, and along the south coast into South Australia.. Observation - Acacia cyclops (Rooikrans) - Southern Africa. Acacia cyclops A. Cunn. Agricultural Research Council, Plant Protection Research Institute, Private Bag X5017, Stellenbosch, South Africa. SOUTH-WESTERN CAPE, SOUTH AFRICA BY P. M. HOLMES*, I. This species is widely invasive in the Mediterranean‐climate coastal vegetation of South Africa that includes the Strandveld vegetation type. Acacia cyclops is one of the 13 species of Australian acacias (Mimosaceae) that have become naturalized in South Africa and are now declared invasive weeds. ... Like A. saligna, this species is a major environmental weed in South Africa, fide C.H.Stirton, Plant Invaders 40–43 (1978). This reduces the number of seeds that are produced. However, many signs (e.g. Leaves phyllodic, apparently simple, glabrous, 3-9 x 0.6-1.5 cm, narrowly-oblong, usually ± straight, sometimes slightly falcate, obliquely mucronate apically, narrowed basally, with 3-5 prominent longitudinal nerves and anastomosing almost longitudinal veins. Large numbers of Acacia cyclops trees are dying along the coastal plains of the Eastern and Western Cape Provinces of South Africa. Abstract Acacia cyclops is an invasive Australian tree in South Africa and a target for biological control using seed‐reducing agents. Abstract Acacia cyclops is an invasive Australian tree in South Africa and a target for biological control using seed-reducing agents. This study examines the fuel properties of two invasive woody alien plants in South Africa to determine how they affect fire behaviour. The red-eyed wattle or western coastal wattle (Acacia cyclops) is an Australian tree.It is in the plant family Fabaceae.It is one of nearly 1000 species of Acacia in Australia. A. W. MACDONALDt AND J. JURITZI * Department of Botany, t Percy FitzPatrick Institute of African Ornithology and t Department of Mathematical Statistics, University of Cape Town SUMMARY (1) Populations of buried viable seeds of Acacia cyclops and A. saligna, invasive aliens of fynbos, were estimated to assess the effects on them … Under the original typification, the name Acacia would stay with the group of species currently recognized as the genus Vachellia. The weevil Melanterius servulus Pascoe (Coleoptera: Curcullonidae), that causes the destruction has been used, since 1991, very successfully in the control of Acacia cyclops in South Africa. Acacia cyclops is one of the 13 species of Australian acacias (Mimosaceae) that have become naturalized in South Africa and are now declared invasive weeds. Includes bibliographical references (leaves 78-94). ex G. Don (Fabaceae, Mimosoideae), originating from Western Australia, is a serious environmental weed in South Africa. Used for stabilization in South Africa, it is spreading on sand and sandstone into coastal bush and heathland. Hop wattle is native to Australia (Victoria, New South Wales, Tasmania).
